🗑
Anticodons   Group of three nucleotides that bind to codons on mRNA during protein synthesis  
🗑
Chromosomes   Bundles of coiled DNA inside the nucleus  
🗑
Codons   Three-letter sequences in mRNA molecule  
🗑
Cytosine (C)   One of three bases that make up the genetic code of DNA and RNA  
🗑

🗑
Start codon   The first codon in mRNA, beginning with the sequence AUG  
🗑
Stop codon   The last codon in mRNA, ending with one of three sequences  
🗑
Thymine (T)   A component of nucleic acid that pairs with adenine in DNA  
🗑
Transcription   The process by which mRNA is produced  
🗑
Transfer RNA (tRNA)   Type of RNA involved in protein synthesis  
🗑
Translation   The process by which RNA directs the sequence of amino acids assembled by a ribosome during protein synthesis  
🗑
Uracil (U)   A nitrogen base found in RNA nucleotides  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
